Can oceanic paleothermometers reconstruct the Atlantic Multidecadal Oscillation? [PDF]
Climate of the Past, 2011 Instrumental records of the North Atlantic sea surface temperature reveal a large-scale low frequency mode of variability that has become known as the Atlantic Multidecadal Oscillation (AMO).

A global-scale multidecadal variability driven by Atlantic multidecadal oscillation. [PDF]
Natl Sci Rev, 2020 ABSTRACT Observational analysis shows that there is a predominant global-scale multidecadal variability (GMV) of sea-surface temperature (SST). Its horizontal pattern resembles that of the interdecadal Pacific oscillation (IPO) in the Pacific and the Atlantic multidecadal oscillation (AMO) in the Atlantic Ocean, which could affect global

Is the Atlantic Multidecadal Oscillation (AMO) a statistical phantom? [PDF]
Nonlinear Processes in Geophysics, 2011 In this work we critically compare the consequences of two assumptions on the physical nature of the AMO index signal. First, we show that the widely used approach based on red noise statistics cannot fully reproduce the empirical correlation properties ...

Winter Eurasian cooling linked with the Atlantic Multidecadal Oscillation
Environmental Research Letters, 2017 In this paper, we analyze observational and reanalysis data to demonstrate that the Atlantic Multidecadal Oscillation (AMO) significantly modulates winter Eurasian surface air temperature through its impact on the shape, frequency and persistence of Ural

A delay equation model for the Atlantic Multidecadal Oscillation [PDF]
Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2021 A new technique to derive delay models from systems of partial differential equations, based on the Mori–Zwanzig (MZ) formalism, is used to derive a delay-difference equation model for the Atlantic Multidecadal Oscillation (AMO). The MZ formalism gives a rewriting of the original system of equations, which contains a memory term.

Theoretical Investigation of the Atlantic Multidecadal Oscillation [PDF]
Journal of Physical Oceanography, 2015 AbstractA weakly damped mode of variability, corresponding to the oceanic signature of the Atlantic multidecadal oscillation (AMO) was found through the linear stability analysis of a realistic ocean general circulation model. A simple two-level model was proposed to rationalize both its period and damping rate.

npj Climate and Atmospheric Science, 2022 Northern Hemisphere (NH) climate has experienced various coherent wintertime multidecadal climate trends in stratosphere, troposphere, ocean, and cryosphere. However, the overall mechanistic framework linking these trends is not well established. Here we

Emerging negative Atlantic Multidecadal Oscillation index in spite of warm subtropics. [PDF]
Sci Rep, 2017 AbstractSea surface temperatures in the northern North Atlantic have shown a marked decrease over the past several years. The sea surface in the subpolar gyre is now as cold as it was during the last cold phase of the Atlantic Multidecadal Oscillation index in the 1990s.

Environmental Research Letters, 2021 The 168 year trends of summer (July–September) sea ice area (SIA) variations in six Arctic regions during 1850–2017 are analyzed. SIA has been significantly decreasing in most Arctic regions since 1850.

Sub‐surface signatures of the Atlantic Multidecadal Oscillation [PDF]
Geophysical Research Letters, 2008 Sub‐surface signatures of the Atlantic Multidecadal Oscillation (AMO) are identified using expendable bathythermograph (XBT) measurements of temperature from the surface down to a depth of 400 m. Basin averaged temperature anomalies in the North Atlantic at different depths display multidecadal variability with a phase shift between temperature ...
